http://doc.powerdns.com/types.html has a few words to say which basically
boils down to "When encoding, the priority field is used to encode the
priority."

For my Jabber Server and the gmysql backend i am running fine with the
following values:
mysql> select * from dns_record where type='SRV' and id=1406\G
*************************** 1. row ***************************
         id: 1406
  domain_id: 11
       name: _xmpp-client._tcp.mandelbrot.zaphods.net
       type: SRV
    content: 0 5222 mandelbrot.zaphods.net
        ttl: 86400
       prio: 5
description:
    dynamic: 0
  ordername:
       auth: 1
1 row in set (0.00 sec)

Via dig this then gives:
_xmpp-client._tcp.mandelbrot.zaphods.net. 86400 IN SRV 5 0 5222
mandelbrot.zaphods.net.
;; Received 116 bytes from 217.197.86.169#53(217.197.86.169) in 10 ms

Service and Protocol in SRV are encoded in the name of the record.
There also is a nice Wikipedia article for SRV that clears this up:
